did you make this course? because you/the maker could have made a mistake while putting in the options for the audio thingy ; P
ah no it’s not my course but i just wanted to mention it just in case it could be changed. i get it wrong half the time it only provides audio since 2 different words both use the same, Lol.
ah : D must be a mistake, maybe you could message the author of the course if he uses this forum?
